This invention relates to ingot molds and particularly to that'typedesigned to cast typemetal ingots of the kind that are fed graduallyinto the pot of a typesetting and casting machine and such as is shown,for example, in my patent for.

Ingot for typesetting machine feeders, No. 2,083,913, dated June th,1937.

My 'invention contemplates the provision of a simple, inexpensive, buteicient mold preferably 0 for use in the casting of individual ingots ofthe A type above described at the printing plant where such ingots areused. The ingots. are customarily cast of the metal obtained fromremelting printing slugs or characters. The ingot produced by the moldof the present inventipn is of the proper shape and size to be used inthe feeding machines and may be readily hung on the hook of suchmachines, while the extreme ends of the ingot are so shaped that theyautomatically drop into the pot by gravity and thereby avoid heating oIthe hook of the machine, the ingot having other advantages such asrequiring no attention on the part oi the operator.

My invention further contemplates. the provision of a mold which isself-levelling and cannot shake or wabble when resting on a supportingsurface, particularly during the operation of pouring metal thereinto.

My invention further contemplates the provision of a mold from which theingot may be readily discharged by a simple turning operation andwithout the necessity for striking the mold.

My invention further contemplates the provision of a mold provided withgauge means for in-v suring the casting of ingots of the proper size,and reinforced against warping, and provided further with means forinsuring the formation of a proper hooi-receiving and completely open.slot, which slot cannot be ifilmed over or finned and in which,therefore, the casting operation may be quickly and efiicientlyperformed.

My invention further contemplates the provision of a mold designed tooccupy a minimum amount of space when not in use and in. which the moldsurfaces are protected from the accumulation thereon of dust, dirt,water, or Qther `foreign matter which not only might contaminate theingot cast in the mold, but which might result in injury to the operatorwhen molten metal is poured thereinto.

The various objects of the invention will be clear from the descriptionwhich follows and from the drawing, in which,

Fig. 1 is aperspective view of my.improvcd mold.

Fig. 2 is a vertical longitudinal section thereof showing the ingot casttherein, partly in section.

Fig. 3 is a vertical section of the same taken on the line 3--3 of Fig.2.

Fig. 4 is a top plan view of one end portion of the mold.

In the practical embodiment of my invention which I have shown by way ofexample, the mold is preferably, though not necessarily, made of asingle piece of suitable metal as by casting or the like. The sides l0and II are each provided with a flat and downwardly and inwardly taperedinner surface as I2 and I3 respectively. The bot-` tom I4 of the mold isprovided with a substantially iiat outer surface I5 and with a ilatinner surface IB extending through the mid-portion of f the mold. At theend parts of said surface I6, the convexly upward bottom surfaces I1Iand I8 -are provided, said surfaces joining the tapered end moldsurfaces I9 and 20 to the remainder of the bottom surface I6. The sidesand bottom of the body of the mold are preferably reinforced to preventwarping, as by means of the ribs 9 arranged vat spaced intervalsthroughout the length of the mold body, and projecting outwardly beyondsaid sides and beyond. said bottom. The outer surfacesof the sides IIJand II may in part be vertical as shown at 8, and in part lnclined ortapered as shown at 'I.

An end nange as 2I is provided at one end of the mold while adifferently shaped end flange 22 is provided at the other end. Each ofsaid ilanges, however, projects transversely beyond the sides I0 and I Iand below the bottom I4, and is further provided with an upwardlyextending pair of projections as 23, 24, disposed above the top surface25 of the sides. The end ange 2l is preferablyv made concave inwardly atits lower edge' 26, the side edges 2'I and 23 of said flange 2I beingcurved convexly to provide rolling surfaces designed to engage thesurface'which supports the mold when said mold is rotated about itslongitudinal axis. One of the lower corners 29, of the ange 2I vservesas a fulcrum point for such rotation, whichcan be readily effected,

by means of the handle 3i when it is desired to discharge thehotingot.The flange 22 is provided with a curved peripheral edge 32 extendingbetween the projections 23, 24 thereof.l

It will be understood that when the mold is arrangedin the position ofvFig. 1, it rests on the corners 29'and 30 ,of the end flange 2| and alsoon the lowermost point of the edge 32, thereby providing a three pointsupport for the mold and but instead, the operator after grasping thehandie 3| need only rotate the mold either in a clockwise orcounter-clockwise direction for a sufficient angle, greater than tocarry the handle 3| past a vertical position, whereafter on release ofthe handle 3|, the mold will drop into an inverted position on to thesupporting surface, to come to rest on the projections 23, 24 ofthe endflanges. By dropping the mold in itsthus inverted position in the lastpart of its rotation by the handle, a shock or blow is given to themold, which in most cases is sufficient to jarthe ingot out of the moldand cause the ingot to drop on to the supporting surface without thenecessity for additionally striking the mold on any manner, orattempting by other means to free the hot ingot from its frictionalcontact with the mold surfaces.

When the mold is thus inverted, neither the top surface 25 thereof norany of the mold surfaces comes into contact with the supporting surface,which may have dirt or Water thereon, whereby the mold is kept clean andneed only be rotated back to the position shown in Fig. 1 ready for arepetition of the operation.

Gauge means are provided for insuring the casting of ingotsvof the`proper size. As illustrated, said means talles the form of thepreferably V-shaped notch 33 made.in one of the sides. as the bottom ofsaid notch determining theihighest level of .the molten metal. Whenpouring, the operator need merely watch the notch 33 without paying anyattention to the remaining parts of the mold and he need merely stoppouring when the metal level 34 reaches the bottom of the notch. Shouldhe inadvertently continue the pouring of metal, excess metal will escapethrough said notch Without increasing the ingot height and withoutdanger lof closing up the slots intended to be formed in the ingot. Bythe provision of said notch, the operator need pay no attention to thecores, later to be described, for forming the ingot slots.

Each of said slots is formed in the ingot by means of a suitable coremember 35 upstanding integrally from each of the mold surfaces I1 and i8at the ends of the mold. Since each of the cores 35 and the partsassociated therewith are identical, a description of one will suflloefor both. The top surface 36 of the core member 3,5 is made preferablyof generally pyramidal or wedge form, the uppermost point, apex or edgethereof being slightly above the surface 25, but below the uppermostpoints of the projections 23 and 24. 'Ihe pitch thus given to said topsurface 36 prevents the adhesion of any metal thereto, should such metalbe inadvertently poured thereon during the operation of pouring metalinto the mold. Furthermore, should the mold become slightly tilted sothat molten metal rises higher than it should along the lateral surface31 of the corey 35, the additional height of said core, given to it; bymeans o`f the sloping surface 36, prevents the bridging of the top ofsaid core by metal, so that the casting of a suitable slot in the ingotis assured, regardless of accidents, or carelessness on the part of theoperator, or due to the mold being out of level.

Said core member 35 does not extend to the adjacent flange 2| or 22,0!the mold, but is connected thereto by a comparatively short and muchnarrower neck 38, the walls of which neck extend downwardly a distanceless than the height of the core to form a pair of substantialiy flatsurfaces 38 and 40. Said surfaces are arranged about midway between thesurface I8 and the horizontal plane passing through the liquid level 34.The various surfaces of the core 35 and of the neck 38 are given asubstantial taper so that the lugs 42 formed on the ingot i. by fillingwith metal the spaces above the surfaces 33, 40 and adjacent the neckare properly beveled and rounded to provide a minimum hook-engagingsurface.

It will be noted that the ingot 4| cast in the mold is provided .withdouble lugs as 42 having roundededges 'adapted to engage the hook of thefeeding machine along a minimum 4area and of such shape that when theingot is melted to the bottom of the slot formed by the core member 35,the end arm portions of the ingot readily slip of! the hook into the potof the typographical machine.

When not in use, the mold stands upright and rests on the flat surfaceprovided by the outer face of theflange 22 and therefore occupies aminimum amount of floor space, the mold surfaces being also protected toa substantial extent from the accumulation of foreign matter therein aswould be the case if the mold were to rest on the oor in the usualmanner. Nor can the mold surfaces come in contact with any water whichmay have been spilled on the floor and which is a source of danger whenmolten metal is poured into the thus wet mold. When the vmold is to beused, it is merely turned into the position of Fig. 1 to rest onv thecorners 29 and 30 and on the bottom of the flange 22 so that it cannotwabble. The operator now pours the molten metal into the mold, watchingonly the notch 33. Should metal be inadvertently poured on the coremember 35, such metal because of the shape of the top surface 3B, runsoi the core back into the mold and cannot form a film or fin to closethe slot in the resulting ingot. When the liquid metal has reached theAbottom of the notch 33, the pouring is stopped, though should anyadditional metal be inadvertently poured into the mold, it willnevertheless fail to close the slot of the ingotv but will escapethrough the notch. After the ymetal has solidified sufllciently, thehandle 3| is merely rotated,

thereby rocking the mold on to the surface 21 or,

28 of the end flange 22, the mold also rocking on the curved edge 32 ofthe flange 2|. When turned sufficiently to overcome the tendency of themold to turn back to its initial position, the handle 3| is releasedwhereupon the mold drops with considerable force the rest of the wayinto its inverted position, producing a hammering effect thereupon whenstriking the supporting surface, that is, when the corners 24 fall on tosaid surface. The ingot, due to the jarring effect thus produced, dropsout of the mold whereupon the mold may be turned back to its pouringposition and the operation repeated.

It will be seen that I have provided a simple, though efficient andeasily manipulated and safe mold, having the advantages hereinbeforepointcific embodiments of my invention, I do not wish to be understoodas limiting myself thereto, but intend to claim the invention as broadlyas may be permitted by. the state of the prior art and the scope of theappended claims.
